Welcome to your interview.
The question is on your right: Simulating a Fair Coin. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Solve this probability brain-teaser: if you have a biased coin, how can you use it to simulate a perfectly fair 50/50 coin toss?
